Description

Technical Field

[0001] The utility model belongs to the technical field of lightning protection equipment, and specifically relates to an adjustable lightning arrester support device. Background Technique

[0002] The lightning arrester is connected between the cable and the ground and is usually connected in parallel with the protected equipment. The lightning arrester can effectively protect the communication equipment. Once an abnormal voltage appears, the lightning arrester will act and play a protective role. When the communication cable or equipment operates under normal working voltage, the lightning arrester will not function and is regarded as an open circuit to the ground. Once a high voltage appears and endangers the insulation of the protected equipment, the lightning arrester will immediately act, direct the high-voltage impulse current to the ground, thereby limiting the voltage amplitude and protecting the insulation of the communication cable and equipment. After the overvoltage disappears, the lightning arrester quickly returns to its original state and enables the communication line to work normally.

[0003] After retrieval, CN219287128U discloses an adjustable lightning arrester device. This adjustable lightning arrester device effectively solves the problem that when the lightning arrester device on the market is installed at a high altitude and often encounters bad weather such as storms, when the lightning arrester is subjected to external forces, it is easy to generate a large instantaneous impact force. Over time, the risk of slippage between the lightning arrester and the fitting will increase, resulting in the lightning arrester losing its function.

[0004] However, through the exploration of the inventor, it is found that this technical solution still has at least the following defects:

[0005] This adjustable lightning arrester device protects the lightning rod by raising and lowering it through a lifting rod in stormy weather. However, in actual use, only lowering the height of the lightning rod cannot achieve an ideal protection effect, and the impurities on the lightning rod cannot be cleaned, thereby reducing the service life of the lightning arrester.

[0028] Such as Figures 1 to 5As shown in the figure, an adjustable lightning arrester support device includes a bottom plate 1 and a lightning rod 2. Above the bottom plate 1, a telescopic mechanism 3 is provided. The telescopic mechanism 3 includes a protective barrel 301, a lifting rod 302, a mounting plate 303, a telescopic rod 304, and a scraper 305. The inner wall of the protective barrel 301 is fixedly connected to the bottom of the lifting rod 302. The top of the lifting rod 302 is fixedly connected to the bottom of the mounting plate 303. The bottom of the mounting plate 303 is fixedly connected to the top of the telescopic rod 304. One side of the mounting plate 303 is fixedly connected to one end of the scraper 305. A connecting plate 306 is fixedly installed on the inner wall of the protective barrel 301. A cleaning brush 307 is fixedly installed on one side of the connecting plate 306. A support rod 308 is fixedly installed at the bottom of the bottom plate 1. A bearing plate 309 is fixedly installed at the bottom of the support rod 308;

[0029] In this embodiment, the number of telescopic rods 304 is four. The telescopic rods 304 are symmetrically distributed at the bottom of the mounting plate 303. The shape of the scraper 305 is T-shaped. The number of scrapers 305 is four. The scrapers 305 are symmetrically distributed on the outer wall of the mounting plate 303. Thus, the height of the lightning rod 2 can be better adjusted, and the stability during movement can be increased. The impurities on the cleaning brush 307 can be cleaned by the scraper 305, ensuring the cleaning effect of the cleaning brush 307;

[0030] Furthermore, the shape of the connecting plate 306 is arc-shaped. The number of connecting plates 306 is four. The connecting plates 306 are symmetrically distributed on the inner wall of the protective barrel 301. The number of cleaning brushes 307 is several. The cleaning brushes 307 are symmetrically distributed on one side of the four connecting plates 306. Threaded holes are provided on the surface of the bearing plate 309. Thus, the lightning rod 2 can be cleaned when it moves into the protective barrel 301, better improving the lightning protection effect of the lightning rod 2.

[0031] Embodiment Two:

[0032] Above the bottom plate 1, a disassembly and assembly mechanism 4 is provided;

[0033] The disassembly and assembly mechanism 4 includes a threaded rod 401, a threaded plate 402, a limiting rod 403, an insulating pad 404, and an insulating block 405. The outer wall of the threaded rod 401 is threadedly connected to the inner wall of the threaded plate 402. One side of the threaded plate 402 is fixedly connected to one end of the limiting rod 403. One side of the threaded plate 402 is fixedly connected to one side of the insulating pad 404. The other side of the insulating pad 404 is in pressing contact with one side of the insulating block 405;

[0034] In this embodiment, a moving groove is formed at the top of the mounting plate 303. The bottom of the threaded plate 402 is slidably connected to the inner wall of the moving groove. The threaded plate 402 is in a T shape. A limiting hole is formed on the outer side of the insulating block 405. One end of the limiting rod 403 is in pressing contact with the inner wall of the limiting hole, so that the threaded plate 402 can be moved better, and then the insulating block 405 and the lightning rod 2 can be disassembled and assembled more conveniently, improving the convenience and facilitating better use.

[0035] Furthermore, the top of the bottom plate 1 is fixedly connected to the bottom of the protective barrel 301. The inner wall of the protective barrel 301 is fixedly connected to the bottom of the telescopic rod 304. The bottom of the lightning rod 2 is fixedly connected to the top of the insulating block 405.

[0036] The implementation principle of an adjustable lightning arrester support device in this embodiment is as follows: When in use, the operator places the device at the required position and uses bolts to pass through the bearing plate 309 to fix it. When in a stormy weather, by starting the lifting rod 302 to work, the mounting plate 303 is driven to move. By the movement of the mounting plate 303, the telescopic rod 304 is driven to expand and contract. By the movement of the mounting plate 303, the lightning rod 2 can be driven to lower and enter the protective barrel 301. After the lightning rod 2 enters the protective barrel 301, the cleaning brush 307 installed on the connecting plate 306 is used to clean the impurities on the surface of the lightning rod 2, so as to better protect and use it. When in a thunderstorm weather, repeat the above steps to raise the lightning rod 2. When the mounting plate 303 moves, the scraper 305 can be driven to move. As the scraper 305 moves, the impurities remaining on the cleaning brush 307 can be cleaned, so as to improve the cleaning effect of the cleaning brush 307 and increase the lightning protection effect of the lightning rod 2, facilitating better use.

[0037] When the lightning rod 2 needs to be disassembled and assembled, the lightning rod 2 is fixedly installed on the insulating block 405, and the insulating block 405 is placed on the mounting plate 303. At this time, by rotating the threaded rod 401, the threaded plate 402 is driven to move in the moving groove. By the movement of the threaded plate 402, the limiting rod 403 is driven to move. As the limiting rod 403 moves, it can be inserted into the limiting hole formed on one side of the insulating block 405, and the insulating pad 404 can be in pressing contact with one side of the insulating block 405, so that the insulating block 405 can be fixed, and then the lightning rod 2 can be fixed. When disassembly is required, repeat the above steps, which is more convenient for the operator to use and improves work efficiency.
